A fully screen-printed, lithography-free manufacturing route for interdigitated back contact silicon solar cells Çiftpınar, Emine Hande; Aliefendioğlu, Ateşcan; Keçeci, Ahmet Emin; Canar, Hasan Hüseyin; Turan, Raşit (2026-08-01) Interdigitated back contact (IBC) silicon solar cells enable high-efficiency device architectures but remain challenging to manufacture at industrial scale due to complex patterning requirements involving lithography, lase...
Study of the effect of ionizing γ-radiation on the structural and vibrational properties of GaS and Yb-doped GaS (GaSYb) single crystals by X-ray diffraction (XRD) and Raman spectroscopy Madatov, R. S.; Turan, Raşit; Tagiev, T. B.; Sedani, Salar H.; Khaligzadeh, A. Sh; Genc, A. M.; Gulen, E.; Mamishova, R. M. (2026-03-01) This study investigates the effects of gamma irradiation on the structural and vibrational properties of GaS and Yb-doped GaS (GaSYb) single crystals. X-ray diffraction (XRD) analysis reveals that irradiation induces sulfu...
Enhanced Passivation of Boron-Doped Polysilicon Passivated Contacts With a Single-Sided J0 of 2.8 fA/cm2 by Dual-Layer Silicon Oxide Structure Shui, Lizhen; et. al. (2026-01-01) Boron (B)-induced interface defects remain a key bottleneck that limits the passivation quality of p-type tunnel oxide passivating contacts (TOPCon), thereby constraining the efficiency of back-contact TOPCon (TBC) solar c...
Simulation of TOPCoRE Solar Cells: Impact of Boron Doping Parameters of P+ Layer Localized Under Front Side Metal Contacts on Cell Performance Muka, Eni; Turan, Raşit; Nasser, Hisham (2026-01-01) This work elaborates on the modeling properties of a Tunnel Oxide Passivated Contact with Rear Emitter (TOPCoRE) solar cells on p-type silicon focusing on the influence of boron-doped hole-selective layers localized under ...
A study of the effect of γ-radiation on electrophysical characteristics of Yb-doped GaS single crystal Madatov, R.S.; Turan, Raşit; Tagiev, T.B.; Khaligzadeh, A. Sh.; Genç, A.M.; Gulen, E.; Mamishova, R.M. (2025-12-01) Doping GaS single crystals with Yb atoms introduces donor and acceptor levels, which dramatically change the electrical conductivity in the temperature range 125–300 K. Additional defect levels are added by gamma irradiati...
Screen printed Ag-doped nickel metallization for industrial n-TOPCon silicon solar cells Unsur, Veysel; Arslan, Melisa Korkmaz; Alloji, Esma; Akgayev, Berkeli; Tokgoz, Halil; Turan, Raşit; Akbayrak, Serdar (2025-08-01) This study introduces an innovative Ag-doped Ni metallization technique for TOPCon silicon solar cells, offering a cost-effective alternative to traditional silver-based contacts. Employing nickel paste doped with only 4 %...
Proposal of dual-gate oxide layered with HfO2: Comparative results with SiO2-RadFET Yilmaz, Ercan; Ristić, Goran; Turan, Raşit; Yilmaz, Ozan; Gurer, Umutcan; Danković, Danijel; Budak, Erhan; Marjanović, Miloš; Veljković, Sandra; Mutale, Alex; Kahraman, Aysegul (2025-07-01) The aim of this study is to develop pMOS dosimeters that can exhibit high performance at high radiation doses compared to traditional SiO2-based RadFETs, for which a dual-gate oxide-layered sensor is proposed. The sensor c...
